Lithium battery module used for handheld electric drill

Abstract

The invention discloses a lithium battery module used for a handheld electric drill. The lithium battery module comprises a cuboid-shaped casing, wherein a lithium battery is mounted inside the casing; an upper cover is clamped to the upper part of the casing; a power supply leading-out terminal is led out from the upper surface of the upper cover, and is inserted into a handheld electric drill casing for providing electric energy; two symmetrical conductive copper sheets are arranged on the outer wall of the power supply leading-out terminal; the conductive copper sheets are connected with the positive output end and negative output end of the lithium battery inside the casing; ventilation meshed holes are further formed in the upper surface of the upper cover; patterns for enabling the lithium battery module to be conveniently held by hands are further arranged on the two sides of the upper cover; a circle of groove used for clamping is formed in the outer edge of the upper cover. According to the invention, power supply is realized by adopting the lithium battery, the electric energy capacity is high, the size is small, the power is higher, the output capability of the handheld electric drill is improved, a relatively hard material can be conveniently drilled, frequent charging is not required, and the use is convenient; besides, the ventilation meshed holes and kidney-shaped vent holes are formed, so that the heat dissipation of the lithium battery is facilitated; therefore, the service life is prolonged, and a good application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, and in particular relates to a lithium battery module used for a hand-held electric drill. Background technique [0002] The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and works, drives the working device through the transmission mechanism, and drives the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates better. Objects, at present, hand-held electric drills are easy to carry and have been widely used. However, the battery storage capacity in the current hand-held electric drills is not strong, the weight is relatively heavy, it is laborious to hold, and it is hard to hold for a long time, and its output power is small. , it is inconvenient to drill holes in relatively hard materials, wh...
